Professional-grade calculators to help you design, plan, and optimize your security camera system. Free, easy to use, and backed by industry standards.
Design your surveillance layout with interactive floor plans. Place cameras visually and see real-time coverage zones.
Calculate exact storage requirements for your NVR system based on camera count, resolution, and retention period.
Determine camera coverage area and viewing angles based on lens focal length, sensor size, and installation distance.
Select the perfect lens focal length for your needs based on DORI requirements and installation parameters.
Planning a security camera system requires careful consideration of multiple factors: camera placement, lens selection, storage capacity, and bandwidth requirements. Our suite of calculators takes the guesswork out of system design.
Based on Hikvision, Dahua, and DORI specifications
Instant calculations as you adjust parameters
No registration required, use as often as needed
Our calculators use industry-standard formulas and data from leading manufacturers like Hikvision. Results are based on typical conditions and should be considered estimates. Complex environments may require 20-30% more storage or different lens selections.
2MP (1080p) is suitable for general monitoring. 4MP provides better detail for recognition tasks. 8MP (4K) is ideal when you need to identify faces or license plates from longer distances. Higher resolution requires more storage and bandwidth.
H.265 (also called H.265+) provides the same video quality as H.264 but uses about 50% less storage and bandwidth. Most modern NVRs and cameras support H.265. If you have newer equipment, H.265 is the better choice.
Start with the Lens Calculator to determine the right focal length for your needs. Use the FOV Calculator to verify coverage at your installation distance. Design your layout with the Camera Planner, then calculate storage requirements with the Storage Calculator.
The Camera Planner allows you to save your designs when you create a free account. For other calculators, you can export results as PDFs or take screenshots for your records.
